Audi A6
The average-sized sedan is not only good quality but a high standard of luxury too. The 4-wheel drive system is the same as that seen in the Quattro and is for sure a stand out feature. The car has no depreciated from $50,000 to $15,000.

Mercedes CL-Class
The CL series is the most prestigious Mercedes two-door model. The SL is a lot sportier, but the CL is actually a GT car which has powerful engines, luxury features with the best quality, and enough space to accommodate four people. That level of prestige, however, comes with a really high price tag. When it started, the base price of the CL was higher than $100k. Right now, for just around $25k (which is the price of an economy sedan), you can get a CL 500 that is in quite good condition.
